and connects into anintegral structure, the upper parts' of the casing lying in opposite' sides of the wheel. The portions 13,* and 13" of the casing are Secured in any suitable Way as by screws 16, to thelmain portion 13.

Secured to flanges 17 on the casing 13 are ratchet, sectors 18 and 19, one on each side ofthe wheel 2. The body of the sector 18 is formed of spring metal and is divided into a pluralt of smaller sectors 21, each bearing a rato et tooth 22. The sector 19 is similarly formed. The sectors 18 and 19, therefore, comprise a plurality of radial spring arms 21 and 23 respectively, each arm separately supporting a tooth. The teeth on each sector 'are normally in aline ment and together form a ratchet sector. The teeth on the wheel `and those on the seotors are spaced equidistant radiali from the shaft. Relatively to each other t e teethl on the, two sides of thewheel are oppostely disposed and the teeth on each sector are disposed oppositely to those on the adjacent side of the wheel, so that the teeth of the wheel may be operatively engaged by the sector teeth and the thrust of the 'sector to be exerted upon the Wheel in one direction orthe other according to which sector is engaged.vv That is, the teeth 22 ofthe sector 18 are adapted to engage the teeth 3 ofthe wheel, and theteeth 24 of the sector 19 are adaptedl to .engage the teeth 4 of the wheel,-

and in' their operative effects, these engagements are in contrary directions.

Means are rovided for -movng the wheel 2 longitudine. ly of the shaft so that its teeth are brou 'ht intoengagement with the teeth of one o theratchet sectors, As previouslexplained, the wheel 2 turns` with, `but movable longitudinally of, the shaft ,6. The extension 12 of the' hub 5 of the wheel pro-j vides means for moving the wheel to the left or to the right, Figui, and the spring' held. latch 26 'adapted to separately en age `the` annular grooves, 27, 28 and 29 in t e shaft 12, holds the shaft 12 and ,the Wheel 2 in the desired position. Fig. lshows the latch enga ing the middle groove 28, the ratchet whee 2 beingl in neutral position between the ratchet sectors 18 and 19. vThe end of the shaft conveniently terminates in a rip 1 such as the knob 31 and a spgjn 32 l in between the opposite end of the ub 5mn the .walls 14 ofthe casi 13- tends to force the wheel 2 toward the eft,` Fi 1. From this it is clear that when the w eel 2 is in enga ement with the right hand sector 19,

or w en the wheel is in neutral position, a release of. the latch 26 from the groove 2'4 or 28 automatically throws the wheel toward the left to engage-with the sector 18. `By raising the latch, pressure upon the grip 31 pushes the wheel to the right, Fig. 1., to

4 Means are lprovided for, oscillating the casing 1B so that intermittent motion ma bo transmitted to the wheel 2 when the w eel is Ain enga ont with either Yone othe ratchet sec ora carried by the casing, the direction of the motion imparted to the wheel and to the platen roll dependlnn r which ratchet sector is s en a d. means includes a lever adapted ed be aotu ated by the hand and it' il desirable that the working Ways be in he same direction. In oacillair-y ing upon vthe shaft 6, the thrust of the casing' 13 upon the wheel 2 may be in eitherI dire@s tion 4forward or backward according to which ratchet sector is engaged.V A reversii ing mechanism is, therefore, interposed he tween the actuating lever and the casm so that the thrust ofthe hand upon the over in one direction is delivered b the casing upon the wheel, in either direc ion.

The lower outside portion it of the ons;

ing 13 carriera lever 34. Alink 35 connects this lever with a rocker 36 pivoted at 87 on the carrie and having a slot 38 in vwhich theend 'o the link 35 isadjustnlile by means of the thumb screw 8l). The grooved rocker 36 is provided Withan Em lll other end of the link 42 is connected by n ball and socket joint to the arm 43 on the shaft 44 ofthe actuating lever 45. The shaft 44 of the actuating lever is oscillatalile in Ar. bracket `hearing 46 which is nrt of the carriage. Without further exp :mation it thrownv to the right in the direction of the arrow A, Fig. the lever 84, Fig. 2, is

pulled over and thecaeing 13 oscillnted bv4 groove retains the wheel in the I thrust of the lever should ali ico ` will be apparent that when the lever l5 is iis 18, the link 35 being connected to the lower end of the rocker as in Fig. 2, it is obvious that a movement of the lever.45 will result in a turning of the platen roll 7 to surface toward the rear (arrow C, Fig. 1 so that the a er on the rolll will be advanced to the ol owing line but bly shifting the wheel 2 to the other side of t e casing to en ge the ratchet sector-19 and moving the lin t `35 to the top .of the rocker 36, the same movement of the lever45 will result in a turning of the platen, top surface forward so that the paper ismovedhackward .to the preced- AIl ing line. A coilspring 47 interposed between the shaft 44 and the bracket bearing 46 returns the lever 45 and connected mechanism to normal position after the line spacing has been accomplished.

By varying the throw of the lever 45 the amount of movement of the casing and hence the platen, can be coiitrolled. A pin 51, Fig. 2, in the shaft 44 contacts with the fixed stop 52 located on the bracket 46 and determines the limit of the spring operated recovery movement of the lever 45. Y Another piu'53, Fig. 1, contacts with the stop 54 located on the sleeve 55 which is revolubiy adjustable on'the bracket bearing 46. The position of the sleeve 55 in which it is secured by the thumb screw' 56, determines the limit of the Vmanually operated actuatin throw of the lever 45. A graduated scale 5% is prcferabl arranged on the sleeve 55. Adjustment o the space independent of the scale is made by loosening the thumb screw,

turning the sleeve to bring the stop 54 into contact with the iin and then moving the lever 45 ,to give t e desired spacing movement of the platen. The sleeve is then locked in that position and subsequent operation of the lever 45 will produce the desired spacingof the platen.

It is clear that if the pitch of the sector and wheel teeth are the same, the shifting of the wheel may by chance fully mesh the teeth, the strai ht sides touching, in which case there wou d he no lost motion between them when the casing is rocked,'but except very rarely this would not happen and so means are provided for securing an immediate operative engagement of the ratchet sectors with the wheel when the latter is shifted longitudinally, thus preventing anyr lost motion between them when Vthe casing is rocked to actuatythe wheel.

In Fig. the teeth 3 of the wheel4 and the teeth 22 of the sector 18 arc shown diagrammatically. rIfhe sector 18 may conveniently be provided with vnine teeth, for the saine` are` the Wheel is provided with o'ne more or' one less, as for instancdte'riptecth. Thatis, the pitches of the sectors` anzi the wheel vary h v 1. With these relative pitches, one tooth of the quadrant will always be in position. to

eli/gage one tooth on the wheel no matter what tbcir relative rotational positions. reviously it has been stated that each tooth i the sectors is individually supported on a radial springarm. T mounting permits a lateral deflection of the teeth and so when the wheel 2 isshiftcd to tho left, Fi 1, the teeth 3 on the wheels-.titer the spaces ietweeii the teeth 22 on the sector in varying de e depending on the distance between the ra ial es of the teeth, but one i V feriastance 3, and 22",Fig./4, wilT always be found to he sultantially in line so that they i5/engage each' other for the maximum dis,

tance. The thrust of the rotation of the sector is communicated to the wheel. through these engaged teeth.

Un moving the wheel out of engagement with the sector, the teeth .on the sector reassuine their aliucd position in the sector by reason of their spring .mounting and iis the wheel is moved to the right, a similar deiicction of the teeth of the ratchet sector 19 results, except a single pair which lyingin line will bc engaged in the manner gust explained.

Other pitches of teeth on the wheel and sectors may be used as desired, but the varia tion between the number of teeth in the sector and the corresponding are of the wheel should alwa s be 1.

W'ith a given setting, the turning of the lever 45 by the hand operates to Vturn the platen roll, and the carriage of the machine may be reversed by the continued movement of the `hand after the lever has reached the limit 'of its rotational movement, in the Well knoivn'manner. With the release of the lever 45 the coil spring 47 effects a recovery of the parts to normal osition, the teeth of the wheel and engage ratchet sector slipping past each other Von the recovery movement owing to resiliency of the mounting for the latter. On reaching the limit of the recovery movement, tivo teeth are a ain in substantial alinement, so that a secon Vmovement of the lever again turns the 'platen through a space corresponding to the partic-y ,ular setting.
